Well, we consider firmware issues to be the same as any hardware
issue. If firmware has a bug that requires us to do things certain
ways, that's really no different from hardware that requires some
insane init sequence.
So why not just say that LINUX_EFISTUB_MINOR_VERSION should be 0, and
just add the comment that versioning doesn't work?
I'm not sure why this was tied into always enabling the initrd command
line loader.
Numbered version checks are a fundamentally broken and stupid concept
anyway. Don't do them. Just leave it at zero, and maybe some day there
is a sane model that actually has a bitfield of capabilities and
requirements.
